GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 289) = 116467
GCD(403, 289) = ( 403 x 289 ) / 116467
= 403 / 289
= 403
Step2:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
Step3:
LCM(1, 976) = 976
GCD(1, 976) = ( 1 x 976 ) / 976
= 1 / 976
= 1
So, Greatest Common Divisor of 403, 289, 320, 976 is 1
